I added the two line of code you suggested to my inkex.py

Код: Выделить всё

import gettext
_ = gettext.gettext

But it still doesn't work

now I get this error:

Код: Выделить всё

Traceback (most recent call last):

  File "/usr/share/inkscape/extensions/gcodetools.py", line 934, in error
    inkex.errormsg(s+"\n")		
AttributeError: 'module' object has no attribute 'errormsg'

any idea?

Yes, I've got some ideas!

First of all, to make it work you can try inkex.py from later versions. Here's inkex.py from 0.48.

inkex.py.tar.gz: (3.25 КБ) 2188 скачиваний

Another way: you can add a stiring into gcodetools:

Код: Выделить всё

inkex.errormsg = lambda x: pass

It seems that inkex has been changed a lot since your version. And we have to think what to do about it.

PS I've got good news, Inkscape's developers asked me to post a request to include gcodetools into inkscape's main package. So probably we won't have this problem anymore.

I've replaced my inkex.py file with the newer one you provided.
But still no success. Now I get this error. I've seen it before on the newer Inkscape with working gecodetools. Usualy saving it as PS and reimporting helps. But not this time.

Код: Выделить всё

No paths are selected! Trying to work on all available paths.

Orientation points have not been defined! A default set of orientation points has been automatically added.

including gcodetools to the main package is good news indeed. But I would be happy to have gcodetools also working with inkscape 0.46 since the official EMC2 based on Ubuntu hardy heron has this version in the repositories. And this version is going to be supported from EMC2 team for still at least a year. Practically everybody using EMC2 now has Hardy installed with inkscape 0.46

EMC2 for Lucid Lynx is still a long way to go. and probably wont be stable any time soon.

Totally agreed, gcodetools must work on inkscape 0.46.

Ok, here's fixed version.
I've added a check if inkex has "errormsg" and if it has not add it.

Код: Выделить всё

### Check if inkex has errormsg (0.46 version doesnot have one.) Could be removed later
if "errormsg" not in dir(inkex):
	inkex.errormsg = lambda msg: sys.stderr.write((unicode(msg) + "\n").encode("UTF-8"))

And fixed one bug which can appear if you do not have any layers at all, it shows when you open svg, that has been made using not Inkscape but some other apps.

Hope it'll work

. I've tried it on Ububtu 9.04 / inkscape 0.46.

Hi !

I think that's be nice to optimize the path...
The cutting process would be more speedy when have many zone to cut...
I've found that jeff Eppler one guys that have programming Axis gui of emc
have done some time ago a generator of photo in "dot" of gcode.. for drilling it with emc...
Nice effects...

http://emergent.unpythonic.net/stippler

But the problems his the time to take for drilling all of the dot...was very very too long..
To win many time in machinning process he have prog an gcode optimizer
that works great... "i found..but perhaps it can be more efficients.."
The interest his that it is prog in python and perhaps this one can be easy to add to gcodetools
which one is in python and be able to output optimize gcode path ...

http://axis.unpy.net/index.cgi/downloads/01103508580

Thank's and have a nice day.

Actually we do have a little optimization. We do not process path in the order they appear in svg. Gcodetools chooses the path having starting point nearest to the ending point of previous path.

Optimization problem is a Travelling salesman problem which is very complex. And has no "fast" solution.

PS Thank you for your help with photos. I'll write you tomorrow or in some day with certain svg or Gcode.

Yes fast optimisation is a very hard problems...
I've not see that's you have ever optimize the path! congratulation.
That's great.
I wait with regards your code and take photos...

The Windows installation files are incomplete. The files that are listed in the download are gcode_tools.inx and gcode_tools.py. The folder containing GCODE tool DEVELOPE does not appear. Also I have the latest version of Inkscape. Any help that you can pass along would be greatly appreciated.

This happens because DEVELOPE version is being developed right now. All features from it will be available at next release. Which I think we will make at the end of the August.

Bu still you can try develop version right now by getting it from our Bazaar repository.
You can do it in several ways:

You can download all necessary files from web interface at http://www.launchpad.net/gcodetools .
Here's the link to the latest at the moment Revision 142 http://bazaar.launchpad.net/~gcodetools ... /files/142
Install bazaar and get the files using it's functions. Once you have installed bazaar all you'll have to do to get the latest developing version just run "bzr branch lp:gcodetools"
See here for more http://doc.bazaar.canonical.com/latest/ ... stallation

After you get all the files you'll need to run "python create_inx.py" in the folder where you have saved the files. This will create several inx files for separate windows.
Then copy all the file into "Program Files\Inkscape\share\extensions\" and restart Inkscape.

Enjoy

!

PS I've moved your question into English support forum from Russian one.
PSS How you managed to post your question in Russian forum. Have you used "Google translate" or not?

Yes I used Google translate, and I'l try to install Bazaar on my Vista machine in the latest version of Inkscape. Otherwise I'll remove the newer copy of Inkscape and revert to the earlier .043 version. Thank you for you response.

Do not revert to v0.43!
Gcodetools works fine with the latest versions of the Inkscape. Even more I think that it works better with the latest versions.
I use both Inkscape v0.47 and v0.47 devel (the future 0.48). Both of them work fine with gcodetools!

PS Bazaar is not a part of Inkscape it's a special tool for developers/programmers/testers which allows version control and distributed development.

PSS what functions are you looking for in gcodetools?

To answer to the request for photo's some engraving done with Gcodetools . Thank's for writing it!.

Rene

Hi Rene!
Thank you for the photos!

Could you attach the svg of the "Milo". I think there's an error in the engraving function.

And how have you done those picture at the first photo? It's just awesome! Is it done with the engraving function or not?

By the way we are planning to make Gcodetools 1.6 release in some days.

Yes nice work !
Could you set better resolution photos...to be able to see the detail of the engraving..

If you can do some tutorial on how you operate if it have more than say's in the forum...nice too..

Thank's for feedback ! and have a nice day.

Hi Guys!
We are proud to make a new release!

Please welcome Gcodetools 1.6

>alfcnc,requested bigger photo, it already has some dents and scratches from being in the bottom of a toolbox for a while so i gave it a quick polish. It was actually the first test i did with gcodetools i think a year ago or so and i dont have the slightest idea how i did it (sorry) The design is by a friend of mine who is in to comics and drawing http://www.sadrabbits.com.

>root, the milo.svg the original output and the edited to run (ad a speed S1 else spindle wil not run and changed feed and depth til now im stil a bit lazy in exactly figuring out how to use gcodetools tool well

I looking forward to test the new version (if i find some time)

regards Rene

Hi Rene!

Unfortunately there's no automatic subdivision inside engraving function. But yo can get better results if you'll do the subdivision yourself.

See the attached image. I've marked bad places with red arrows and good ones with green. You can notice that the more knots you add the better result you'll get. But the calculation time depends at n^2 where n is knots number. So if you increase knots number in two times calculation time will be 4 times longer.

Also it's better to do Path->Break Appart for isolated paths. So they will be calculated separately and calculation time will be m^2+n^2 instead (m+n)^2= m^2 + n^2 + 2*m*n so you'll have 2*m*n calculation time benefit (n,m knots number of separate paths).

Of course all this make sense only for large paths. But keep that in mind

.

To add more nodes use Extensions->Modify path->Add nodes. You can choose from two Division methods either by seg. length or by segment number.

Ah,that is how to solve it ! I'l keep that in mind the next time. I noticed that strange behaviour, but as the result was fine by me i dint look further.

Fresh bug fix:

Orientation points now has it's own units selector.
Parameterize Gcode now generates correct Gcode:
Код: Выделить всё
```
G00 X[9.2202383*#8+#10] Y[9.4568*#7+#12]
```
instead of:
Код: Выделить всё
```
G00 X9.2202383*#8+#10 Y9.4568*#7+#12
```

You can get latest version Gcodetools 1.6.01 at the header of this thread.
